During the last year, I faced many performance issues at customer sites with their applications. To solve the issues, I had to implement some workarounds because in most cases, the application code couldn't be changed.
As Oracle 12c is now available since more than 2 month, I decided to focus on how this new release will help our customers to solve their performance issues. I will present you 3 real customer cases reproduced in lab where Oracle 12c will solve the issues in a serie of 3 articles:
- Adaptive execution plans
- Histogram precision
- Histogram on varchar2 column
These 3 real customer cases will be presented during my session "Solving critical customer issues with the Oracle 12c Optimizer" at the Oracle Open World 2013
